Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 150mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A
The AirTAC SAIF80X150-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, offering an effective flow of Cv 1.40. Driven by an AC220V terminal coil drawing 3.5 VA, it responds in 0.05 s with an IP65 rating. Because the cylinder body rates to 1.0 MPa but the integrated valve limits operation to 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. At 0.5 MPa, the 80mm bore generates 2513 N of push force and 2268 N of pull force.
By integrating the valve directly on a manifold block, this unit switches itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and note the valve port is 1/4" while the cylinder port is 3/8". Factory set to retract the rod when the coil is energised, the 5/2 valve can be repositioned to extend-when-energised depending on your control logic.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large machines by self-switching the 80mm bore directly at the station, reducing tubing runs and panel space.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for holding heavy workpieces, using the integrated 4M310-08 valve to cycle up to 4 times per second.
Retrofit Automation
Ideal for upgrading older lines where running new pneumatic tubing back to a central panel is costly, requiring only a single 220V electrical signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A the Right Choice?
Choose this 80mm bore if your application requires high thrust (2513 N push at 0.5 MPa) but you want to step down from the 100mm bore (3927 N push) to save envelope space. A self-valved SAIF beats a separate cylinder and remote valve when decentralization matters, cutting tubing runs and wiring complexity. Select the AC220V terminal entry for standard factory power grids. To replace this unit, match the 80mm bore, 150mm stroke, 1/4" valve port, AC220V terminal coil, PT thread, and no magnet (-S). For strokes of 150mm or greater, ensure adequate guide support to prevent rod side-loading.
Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the SAIL lock or BSAI clamp-lock cylinder series instead.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF80X150-08A FAQ
The 80mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not hold the load without live pressure. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised. For true position holding, use a SAIL lock cylinder.
